Viper

Viper or his Military name Zipline 28 was presumably a terrier and one of the 4 Wing leaders in Zipline Squadron.

At some between 1:23AM and 2:00Am, Zipline squadron was deployed along with 3 other squadrons to defend against 30 incoming Ridgeback Fighters. During the engagement the Captain of Zipline Squadron (Captain Pattle) and fellow Wing Leader DJ were killed. Wing leader Heartmann ordered a retreat as the group suffered many more casualties. However Viper and 1 other pilot (Cooper Stanley) stayed back to give the pilots enough time to retreat. Cooper Stanley was killed very quickly while Viper managed to destroy 2 Ridgeback fighters (The first pilot to ever do so). However on the attack run, Viper suffered severe damages to his ship. His cockpit soon exploded open releasing him into space where he presumably suffocated.
